    (2)

    Any party requesting permission to install or operate lighting fixtures within the public right-of-way shall furnish plans specifications to the utilities coordinator for approval. Should the utilities coordinator disapprove a request to install or operate lighting fixtures within any public right-of-way, they shall communicate disapproval in writing to the party requesting approval. The written communication shall include specific reasons for disapproval. Any disapproval of a light or lighting system by the utilities coordinator may be appealed to the board. If any party desires to appeal an adverse decision by the utilities coordinator within 30 days from the date following the written notice of disapproval, and it shall be the responsibility of the utilities coordinator to transmit, forthwith, to the board all papers and allied documents constituting the record upon which the action appealed was taken and to ensure that the appeal is promptly placed upon the agenda of the board for its determination. The board may reverse or affirm, wholly or partly, or may modify, the order, requirement, decision or determination appealed from.

    (3)

    Roadway or street lighting luminaries or fixtures installed within the public right-of-way as "security lights" for the purpose of lighting areas other than the public streets, shall be mounted on the side of the pole opposite from the street and shall be oriented in such a manner to ensure that the lateral light distribution pattern is parallel to the street and the vertical light distribution, at the initial light source, is perpendicular to the street, so as to protect the users of the street from objectionable glare. The approval of the utilities coordinator shall be obtained before installation of these lights.

    (4)

    Other lighting fixtures to be installed within or outside of public right-of-way for whatever purpose shall be installed and operated in such a manner to prevent glare from being a hazard to or interfering with the normal use of the public right-of-way.
